Energy

The Lower Mekong countries are hungry for energy. Between 2010 and 2035, demand is projected to double from 157.8 Mtoe (million tons of oil equivalent) to 319.6 Mtoe, concentrated heavily in Vietnam and Thailand.1 Demand will be highest for combined agriculture, commercial and residential needs, followed by industry and transport.

This increased demand has implications for energy trade and energy security within and between the Lower Mekong countries. A stable supply of clean, efficient, and cost-effective energy is therefore fundamental for sustainable economic growth and development in the region.  

Energy sources

Fossil fuels (coal, oil, natural gas) remain the major energy source in the Lower Mekong countries, followed by biomass (firewood and charcoal) in Cambodia, and hydropower in Laos and Myanmar. The demand for coal is projected to overtake natural gas and rise sharply to 28% of the primary energy mix by 20352. This would represent nearly one-fifth of the global growth in demand for coal. Based on current trends, the domestic demand for fossil fuels also signals increasing reliance on fuel imports. In Thailand alone, net oil and gas imports totaled US$30 billion in 2011 and are projected to reach US$100 billion in 2035.

Reliance on coal

Reliance on coal as an electricity source is increasing in the region, despite its lack of popularity elsewhere in the world. The decline in coal prices, combined with the region’s growing demand for electricity has seen governments commit to expand coal-fired power sources, at the same time as they are committing to higher levels of renewable energy (see Energy supply below). In 2011, 21.1% of Vietnam’s electricity production came from coal.3 Thailand has plans for at least three additional coal-fired power plants in the southern provinces of Lampang, Krabi and Thepa.4  

Energy supply

In terms of energy supply and trade flows in the region, Laos is the largest volume exporter of electricity and the most competitively priced supplier. Thailand and Vietnam are reliant on imports from other countries, particularly from hydropower generation, to meet their rapidly growing electricity demands. Cambodia has limited domestic energy production and so it relies on imports.5 Consequently, Cambodia also has the highest electricity tariffs in the region, with costs in the provinces tending to be higher than in Phnom Penh. Meanwhile, what Cambodia, Laos and Myanmar lack in domestic fossil fuel supply, they are working to make up in renewable and hydropower energy production. Laos plans to increase its share of renewables by 30% by 2025, which includes a 10% target for using biofuels in transport. Myanmar intends to increase its share of renewable power generating capacity to 18% of its energy mix by 2020.6

Access to electricity

Access to electricity varies widely, ranging from near universal access in Thailand and Vietnam at 99.7% and 96%, respectively, to 66% in Laos, 48.8% in Myanmar, and a mere 31.3% in Cambodia.7

Millions of Cambodians—up to 85% in rural and remote areas—are still off the electrical grid. They depend on biomass for domestic cooking8 and automobile batteries, kerosene lamps and candles for lighting.

In the last decade, Cambodia and Laos have rolled out extensive rural electrification programs, using a combination of transmission grid extension and off-grid systems such as mini/micro hydropower, biomass gasification and solar. These have  primarily followed national agendas, and contributed little to regional connectedness, leading to uneven access and distribution of energy resources and a mutual import-export dependency among the Lower Mekong countries.

Regional energy initiatives

Several regional energy initiatives are aimed at addressing this issue. Of most importance is the ADB’s Greater Mekong Subregion (GMS) Energy Sub-Sector Program, which will expand national transmission grids in the GMS countries (the five Lower Mekong countries plus the Chinese provinces of Chang Du and Yunnan) to facilitate a cross-border grid network, energy market integration, and cooperation on energy security and sustainability in the region. The Lower Mekong countries are actively involved in projects associated with the GMS Energy Sub-sector Program and ASEAN’s various energy bodies under the intra-governmental ASEAN Centre for Energy (ACE).
